Answer:
It is better to drive a large SUV in stead of a smaller car in icy conditions, because the large SUV contains enough friction of force to drive in the snow on the ground. The mass of the car also plays a huge effect on this because then it does not slide off the road. The large tires on the big SUV make you ride smoothly through the snow and ice. With driving a smaller car though, the old tires have already been through a lot of driving, so this makes driving the car rough on the road. This also makes it so there is not a normal force in the wheels, so this means the car does not go at its normal speed, and this could cause an accident, or the rough tires could cause a fire when driving.
Trust me on this. I am 17, and I drive a Nissan Armada as my first car. Life changing. Happy Holidays!

Answer:
c) F = 16000 N
Explanation:
For this exercise we use Newton's second law
F = ma
they tell us that adding the other wagons the acceleration of the locomotive must be maintained
F = m a
by adding the other four wagons
mass = 4 no
therefore to maintain the force you must also raise the same factor
Fe = 4Fo
Fe = 4 4000
F = 16000 N
Answer:
1) , 2)
Explanation:
1) The kinetic energy due to the rotation is:
Where and are the moment of inertia and angular speed, respectively. The moment of inertia of the circular cone is:
The kinetic energy is:
2) The moment of inertia of the ellipsoid is (where a is the major semiaxis):
The kinetic energy is:
C = Q/V, and since C is a constant, if voltage is doubled, charged will be doubled as well. Therefore charge will be 2Q
Answer:
It is difficult to magnetize.
